Inventors Are Really Thinking.
The air umbrella, created by Je Sung Park and Woo Jung Kwon, is a portable rod that allows you to create a canopy of air to protect yourself from the rain. The hollow rod, when functioning, sucks air in from the bottom and then blows it out from the top in order to create the air canopy. This product allows you to control the size of the canopy, along with how long you want the rod of your umbrella to be.
While this is in a concept stage, it certainly can be improved upon to become part of every day use. It keeps the canopy above you up to 10 miles per hour wind. Of course, regular umbrellas do not handle that very well unless you got the newer ones with the air slits on the canopy.
You can control the length of the stick and the size of the air canopy.
While the inventors are proposing that this is eco-friendly, I believe it has a way to go to call it that. Maybe on the edge of sustainable with the recharging of the battery.
There are many other types of umbrellas out there but I thought what a great concept to share with you.
